12-STAGE

BINARY RIPPLE

COUNTER

The MC74AC4040 consists of 12 master-slave flip-flops. The output of each

flip-flop feeds the next and the frequency at each output is half that of the preceding

one. The state of the counter advances on the negative-going edge of the Clock

input. Reset is asynchronous and active-high.

State changes of the Q outputs do not occur simultaneously because of internal

ripple delays. Therefore, decoded output signals are subject to decoding spikes

and may have to be gated with the Clock of the MC74AC4040 for some designs.

• 140 MHz Typ. Clock

• Outputs Source/Sink 24 mA

• Operating Voltage Range: 2.0 to 6.0 V

• High Noise Immunity
